' DISPENSING AND MIXING DEVICE.

Specification of Letters Patent.

Patented Dec. 2c, 1916.

Application filed November 15, 1915. 3 Serial No .61,458.

' To all whom a'may concern:

Be it known that I, LEON a citizen of the United States, residing in the city and county of San Francisco and State of California, have invented new and useful Improvements in Dispensing and Mixing Devices, of which the following is a specification.

This invention relates to a. dispensing and mixing device. I

One of the objects of the present invention isv to provide a simple, substantial, cheaply manufactured dispensing and mixing device whereby soft drinks, such as carbonated water containing a flavoring syrup may be mixed and dispensed.

Another object of the invention is to provide means for varying the quantity of flavoring syrup delivered so that drinks of any strength or richness may be drawn.

Further objects will hereinafter appear.

The invention consists of the parts and the construction and combination of parts as hereinafter more fully described and claimed, having reference to the accompanying drawings, in which- Figure 1 is a front view of the device. Fig. 2 is a vertical section of the mixing valve on line 22 of Fig. 3. Fig. 3 is a similar section on line 3-3 of Fig. 2. Fig. 4 is a detail view of the regulatingscrew.

Referring in detail to the drawings, A indicates a valve casing of suitable shape and construction, through which extends a tapered plug valve 2, which is adapted to be turned by means of a handle 3. Formed on the lower end of the casing is a nozzle 4, and formed on the upper end of the casing is a socket 5 which is adapted to receive the neck 6 of a reservoir 7, of suitable shape and construction, which is provided with a removable cap 8. The neck 6 of the reservoir may be secured in any suitable manner but is preferably cemented in the socket, as indicated at 9.

10 indicates a vertically disposed passage which communicates with the neck of the reservoir at one end and passes through the nozzle 4 at the other end. This passage is adapted tobe opened or closed by means of the plug valve 3 which has a similar passage 11 formed therein. Formed on one'side of the casing, at right angles to the longitudinal axis of the valve 2, is an extension 12 which is entirely threaded to permit it to bev connected with a pipe 13 which is connected M. VooRsANonR, v

with a source of liquid supply, hereinafter to be described.

Formed in the extension 12 is a central passage; 14 which opens. into pipe 13, and formed in the plug valve is an angularly disposed passage 15 which communicates with the central passage 11, at one end, and with the passage 14, at the other end. Turning movement of the valve, by means of the handle 3, will bring passages 10 and 11 out of register and similarly passages 14 and 15 out of register, thereby cutting out communication between the reservoir 7 and the supply pipe 13.

Mounted on the upper end of the valve casing, a suitable distance below the socket ner end is adapted to partly open-or close the central passage 10, or, in other words,

is a regulating screw 16. This screw passes through a stuffing box 17 and its inregulatethe amount'of fluid which may pass from the reservoirthrough the valve 2.

In operation, referring to Fig. 1, a double arrangement of the device as a whole is shown. Each valve casing, with its connected reservoir 7, is carried by a pipe 13,

which in turn passes through a pedestal 18 mounted on a base 19' of suitable construct on. A pipe 20. passing through the pedestal connects with the pipes 13 and the connected valves, and the opposite end of pipe 20 may be connected with a tank containing carbonated water, either hot or cold.

The device as a whole is particularly constructed for dispensing soft drinks. The

reservoirs 7 are, therefore, filled with syrups of different flavors. WVhen it'is desired to draw a glass, it is only'neces'sary to turn the connected valve3 until passages 10 and 11 and 14 and 15 register; this registry being assured by providing a pair of lugs 22 and 23. Turning of the valve until the lugs engage insures perfect register of the passages. The carbonated water under pressure entering through pipes-2O and 13 and passing through passages 14 and 15 discharges on an angle into the vertically disposed passages 10 and 11. The flavoring syrup from the reservoir will in this manner be permitted to pass by the regulating screw 16 and through the valve where it will be thoroughly mixed with the carbonated water as it discharges from the nozzle 4. An entraining action is produced by the angular discharge caused by the relative position of the passages 11 and 15.

From the foregoing it will seen the v s y l p ao l l by g av but also by the ent'raining or suction action produced. It is, therefore,'. possible. to em a 5 ploy syrups of varying degrees of thickness. 7. -.Q ii{ricl 1Iiess.;r The provision-of the regulating screw 16 permits the q uantity of syrup sup- N plied to be varied, in this'manner i'naking'it" possible/t0, serve drinks ,ofany' richness or v ing can be cleaned out at any time by merely iturni'ngthe valve to a position'where the 20 upper endo'fpassage 15 will'register with the passage 10 and the lower'end of passage 11 with passage 14. The carbonated water 7 under pressure will this manner flush up through passage, 10, by thewregulating screw, and into the reservoir whlch can bethor- 'o ughly cleaned, jThe forcing of the water through the passages and by'the regulating; jscrew at the same time causesthese to be 'tho'roug y cleaned" and reversing of the valve to'f the position shown in Fig." 3 permits the contents to be drawn out before the reservoir is again charged with flavoring syrup.

VVhile the present dispensing device is" shown as fitted with tWOIGSBIVOllS and mix ing valves, itis possible that any suitable number of samemay be used, Also I wish it understood that the device may be used a for compounding liquids of any nature and 40 that I do not wish to limit its application to the serving of beverages alone.

The materials and finish of theseveral parts of the apparatus are such as the eX-- p rience and'judgment of the manufacturer I may dictate;

Having thus described my invention, what This device is simple cheap to'manufacmm r cut is lfIn combination with a casing having a vertical g-passage extending through its top .and bottom and a right-angularjpassage -..l ead1ng; into said vertical passage and through a sideof the casingQa syrup reser- "voir" communicating with the upper end'of the vertical passage, meansto connect said right-angular passage toa source of pres-' su're, and a valve, at the intersection of said two? passages," said valve having a substantially-"straight adiametrical 'passage and] an "inclined passage leading from said diam'e't'ri- 'c'alpassagethrough' a side of the valve whereby in one position the inclined passage extends downwardly from the right-angular passage to convey fluid pressure to the lower end 01" the vertical casing passage, and in a second position extends upwardly fromthe right'angular passageso as to convey fluid pressureit'othe upper "end of-the vertical casing passage'and into-the reservoir to cleanse the'lattein' Y 1 2. In a d sp'ensmgdevme, 2],:(32lS1I1g having I a vertical and a lateral passagew-hl'ch meet at a common point, a syrup reservoir con- 'necte d 'to theupper endof the vertical passage'and the lateral passage being for connection to asource or pressure, and-a valve at said common point having passages which inone position communicate with-each of thevertical andlateral passagesto discharge from each and which in a secondp'o sition establishes communication between the source of pressure and syrup reservoir to allow cleaning of the latter and closes the lower end of said vertical passage;

In testimony whereof I have hereunto set my hand in the presence of two subscribing witnesses V 7 r p LEON M. VOORSANGEB;
